A hand-held component 2 is distributed on the outer side and the rear end of the cutting machine main body 101. The hand-held component 2 is used to provide a holding position for lifting the hand-held cutting machine 1 in different directions, so as to realize different directions of the cutting positioning groove 103;

[0028] The hand-held component 2 includes an adjustable lifting unit and a rear-end reinforcement unit;

[0029] The adjustable lifting unit is used to provide a holding position for lifting the cutting machine main body 101;

[0030] The rear-end reinforcement unit is used to lock the position of the adjustable lifting unit, and the operator holds the rear-end support unit with the other hand to provide a balancing force for the cutting machine main body 101;

[0031] The adjustable lifting unit includes an arc-shaped seat 201, an arc-shaped rail groove 202, a lifting handle 203, and a T-shaped slider 204;

[0032] There are two arc-shaped seats 201, and the two arc-shaped seats 201 are symmetrically fixed to the outer top of the cutting machine main body 101. The arc-shaped rail groove 202 is formed on the inner side of the arc-shaped seat 201. The T-shaped sliders 204 are symmetrically fixed to the bottom ends of both sides of the lifting handle 203. The lifting handle 203 is limited and slidably connected to the inner sides of the two arc-shaped rail grooves 202 through the T-shaped sliders 204;

[0033] Through the cooperation of the T-shaped slider 204 and the arc-shaped rail groove 202, the lifting handle 203 can move along the track of the arc-shaped rail groove 202.
